Problems solved by technology

[0004] The sericulture industry in my country is very developed, but the traditional silk has a single function and narrow application fields.
The new silk material developed by applying various modern physical, chemical and biological methods has broadened the application range of silk, but the operation is too complicated and consumes a lot of manpower, material resources and time

Embodiment 1

[0023] An in-situ enhanced natural silk, the preparation method of which is as follows: freshly picked mulberry leaves are washed and dried, and carbon nanotubes are evenly sprayed on them (the mass ratio of carbon nanotubes to mulberry leaves is 1-10:100 ), and then fed mulberry leaves containing carbon nanotubes to silkworms ( figure 1) . Directly obtain natural reinforced silk by silk spinning method ( figure 2 Below), he is different from the appearance of pure natural silk ( figure 2 superior).

[0024] The mechanical properties of the in-situ reinforced natural silk obtained by the above method are at least 1 times higher than that of ordinary natural silk ( image 3) .

Embodiment 2

[0026] A kind of natural conductive silk, its preparation method is as embodiment 2. This method directly obtains natural conductive silk, and its resistance is 24% smaller than that of natural silk obtained at the same time (Table 1).

[0028]

Embodiment 3

[0030] A kind of magnetic natural silk, its preparation method is as follows: freshly picked mulberry leaves are washed, ferroferric oxide powder is evenly coated on the mulberry leaves (the mass ratio of ferric oxide powder to mulberry leaves is 1-10 : 1-100), and then feed silkworms directly. The magnetic natural silk is directly obtained by the spinning method.

Abstract

The invention relates to a method for preparing natural functional silk by utilizing living silkworms to directly spin. The method comprises the following steps: applying functional materials on mulberry leaves through spraying or coating to obtain functional mulberry leaves; and feeding silkworms with the functional mulberry leaves and utilizing the silkworms to directly spin, thus obtaining the natural functional silk. The method has the following beneficial effects that the method is simple and convenient to operate, is simple, is low in production cost and can be used for large-scale production; and the obtained natural functional silk is a natural product, retains the characteristics of natural silk, is harmless to human bodies and simultaneously has special functionality.

Description

technical field [0001] The invention belongs to the field of silk preparation, in particular to a method for preparing natural functional silk by direct spinning of live silkworms. Background technique [0002] Silk is a continuous long fiber that is solidified by secreting silk liquid when cooked silkworms make cocoons, also known as "natural silk". Like wool, it is one of the earliest animal fibers used by humans. According to different foods, it is divided into silkworms, tussah silkworms, cassava silkworms, camphor silkworms, willow silkworms, and celestial silkworms. [0003] Silk is one of the products of ancient Chinese civilization. It is the lightest, softest and thinnest natural fiber in nature. It can easily return to its original shape after removing the external force. use. Mulberry silk is mainly composed of animal protein, rich in 18 kinds of amino acids necessary for the human body, can promote the vitality of skin cells, prevent vascular sclerosis, long-te...
